This site is dedicated to the
preservation, repair and everyday use of Vintage 1950's - 80' Stroboflash I, II, and IV photographic
strobe units as produced by the Strobo Research Company of Milwaukee, WI and
later by Graflex Inc. of Rochester, NY.
Bring your 20, 30, 40 even 50 year old Stroboflash in to the
21st century. Replace those really EXPENSIVE old Eveready 489's with a
"state of the art" 12v/24v to 450v switch mode power supply
(SMPS). That's right!
I just LOVE Stroboflash, the finest portable photographic strobe
light ever designed. This is a brand new state of the art rechargeable power supply
that will fit right in the Stroboflash II or Stroboflash IV
case. RBPS plugs right on the existing battery connection
pins of the Stroboflash pack. No wiring required. Just
add batteries and start shooting.
Uses a widely available 12v rechargeable Nickel Metal
Hydride (NiMH) batteries. Recycle time
using a Stroboflash IV on FULL power is 4 seconds!! 1/4 power is
< 2 seconds. Flashes per
charge are in excess of 200!! Up to 1000 discharge /
recharge cycles. 81 cents per 1000 flashes!
Designed and Made in USA!

RBPS units today!!! I guarantee you will LOVE them!!"

|In an effort to save you money and keep
things simple we do not sell the batteries and chargers.
These types of batteries are widely available on the
internet and from hobby shops. You can pretty much use
any battery as long as it can output at least 4aH at
12volts and will fit in the Stroboflash case. We suggest
NiMh batteries but NiCd (a little cheaper) or Lithium
(expensive!) will work just fine.

12v Battery and Smart Charger Combo:
Alternate Battery sources:
and chargers are available at most hobby shops. They are
used for robots and remote controlled cars. Any 12v NiCd
or NiMh battery pack will work (make sure it fits in to
your case!). Must be minimum 2500 mAh. 5000mAh or larger
is best. 12v lead acid, lawn mower or car battery is
great too but probably wont fit in the Stroboflash case.

Complete 200 Watt Second Stroboflash IV unit including Head.
(RBPS II and Battery not included.)
The best strobe light in Photography!
New 21st Century technology!
The old, heavy, capacitor pack has been replaced with a 21st
century printed circuit board and new modern light weight
capacitors. Same 200 Watt Second power as the original with half
the weight. This is what is inside the refurbished Stroboflash
IV. Power selector switch is protected against arcing by large
solid state rectifiers. No more burned switch contacts!
Here is what is included in the refurbished Stroboflash IV.
* Refurbished capacitor pack. New power selector switch,
printed circuit board, new capacitors. Coil cord is vintage but
tested and working. Vintage plastic case may or may not be
repainted depending on condition.
* Refurbished Stroboflash head with solid state trigger and
new trigger capacitors for 21st century reliability.
If you are going to use a Stroboflash with a modern digital
camera you must use a Wein Safe-Sync (available from B&H and
Adorama) between your camera and the sync cord connected to the
Stroboflash head. Most digital cameras can only handle less than
12volts at the PC socket or hot shoe. Stroboflash is MUCH higher
Stroboflash IV refurbished unit only $ 175.00 US
